How to Change Text Size on Mac: A Simple Guide for Beginners

Have you ever looked at your Mac and thought, “Why is everything so tiny?” You’re not alone. For many beginners, the default font size on a Mac can be surprisingly small. But here’s the good news: learning how to change text size on Mac is quick, easy, and doesn’t require any tech experience.

Whether you’re reading emails, browsing your favourite websites, or sorting through photos, making the text larger can turn your Mac from frustrating to friendly.


Make Everything Bigger with Mac Display Settings

If everything—icons, windows, menus—feels too small, adjusting the Mac display settings is the best place to start.

Step-by-Step Instructions:

  • Click the Apple menu in the top-left corner of your screen.
  • Choose System Settings (or System Preferences on older versions).
  • Select Displays.
  • Look for the Text Size slider or the Display Resolution options.
  • Drag the slider toward “Larger” or select “Larger Text.”

Pro Tip: If you’re using macOS Sequoia, you’ll see a live preview before you commit to the new size—super handy!


Make Text Bigger in Safari While Browsing

Reading news, blogs, or recipes online? You can zoom in to make web pages easier on your eyes.

Two Easy Ways to Zoom in Safari:

Option 1: Keyboard Shortcuts

  • Press Command (⌘) + Plus (+) to zoom in
  • Press Command (⌘) + Minus (-) to zoom out

Option 2: Set a Default Zoom Level

  1. Open Safari.
  2. Click Safari in the menu bar > Settings.
  3. Go to the Websites tab, then choose Page Zoom.
  4. Set your favorite sites to open automatically at 125% or 150%.

👉 Frank’s Tip: “I set news sites to 150%, and now I don’t have to lean forward like a detective every morning.”
